To all whom it may concern:

Be it known that I, HERMAN A. Summon, a citizen of the United States, and residing at Highland Park, in the county of lVayne and State of Michigan, have invented a new and Improved \Vashing-Machine, of which the following is a specification.

The present invention relates to a washing machine wherein the washing is accomplished in' a cylinder that is mounted in a tub and arranged to rotate about a horizontal axis. It consists in certain means for detachably connecting the cylinder to its driving shaft and sealing the joint between the driving shaft and the tub; also in a new and improved closure for the cylinder;

also in certain other details of construction shown, described and claimed.

This application is a division of my ap plication on washin machines, Serial Num ber 158,607, filed arch 30, 1917.

In the drawings, Figure 1 is a plan view showing a preferred embodiment of the invention, the closure for the cylinder being removed. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a fragmentary longitudinal central section of the inner drum showing the driving shaft and the sealing means. Fig. 4: is a fragmentary section on the line 4-4 of Fig. 3. Fig. 5 is a section on the line 55 of Fig. 1. Fig. 6 is a perspective view of the closure.

'The tub which is supported on legs 1, 2, includes the trough-shaped body 1 and the end walls 5. Mounted to rotate within the tub about a horizontal axis is a washing cylinder that preferably includes the metal body portion 15 and ends 16, one of the latter having projecting therefrom a spindle 18 which is supported in a bracket 19 on the inner face of the tub. The other end of the tub has riveted thereto a bracket 20 which is shaped to detachably receive a tapered nut 21 rigid on the end of the cylinder driving shaft 22 that passes out through the end wall 5 of. the tub. The driving shaft turns in the inwardly projecting boss 24 of a casing element 25, leakage between the shaft and boss being prevented by a packing nut 26 (screwed onto the nut 21) 28. The bracket 20 includes the outwar ly projecting ribs 30 and 31 which are joined by the rib 32; it also in-= cludes a rib. 33 that does not, however, project as far outwardly as do the other ribs; and which has an inclined face 34. It will be noted that the ribs 30 and 31 stand at an angle of to the ribs 32 and 33, and that the rib 33 is spaced from the rib sufficiently to form a pocket in which the tapered nut is snugly received. When the cylinder is to be put into the tub it' is lowered the cylinder is of course turned in the same direction. In detaching the cylinder, it is only'necessary to press the end of the tub outwardly until the rib 33 clears the nut after which the cylinder may be lifted out, as is obvious. I

The. cylinder preferably includes the wooden paddles 36 (as shown, four in munber), one end of each of which is shallow.

The deep ends of one pair of the paddles alternate with the shallow ends of the other. The portion 15 of the cylinder is provided with a longitudinal opening, along the edges of which a series of headed screws 38, together with a screw 39 having a wing nut 40, project. A closure 41 for the opening has the circumferentially extending reinforcing plates 42, the-outer ends of which are slotted at one side as indicated at 43 to allow them to be slipped endwise beneath the heads of the screws. Upontightening up on the Wing nut the closure is, of course, clamped firmly in position.

The cylinder driving shaft 22 has its outer end loosely mounted in the hub of a bevel gear 67 that is, in turn, rotatable in a bearing 68 formed on the casing element 25. The inner face of the hub of the gear 67 is provided with clutch jaws with "which jaws 69 on a. clutch member 70 engage when said clutch member is in one position. The lat ter is keyed on the shaft 22 and may be shifted longitudinally thereof by a crank 71 which carries a roller 72 that projects into a circumferential groove 73, in the clutch member. A lever 74: affords means for, manipulating the crank, and means (not shown) automatically holds the crank either limit of movement.

The gear 67 is driven in any suitable Way, for example, as shown in my previous application above identified, i

The details of construction maybe varied considerably Without departing from the spirit of" the invention, and I do not, there fore, wish to be limited except as indicated by the subjoined claims,

I claini:

1. In a device of the character described, a frame, a tub supported by said frame, a cylinder rotatable in said tub about a horizontal axis, a cylinder driving shaft co-aXial with said cylinder and projecting through the end Wall of the tub, a nut on the inner end of said shaft, a bracket secured to the adjacent-end of the cylinder, said bracket having therein a socket in Which said nut is detachably received, said socket having a plurality of Walls conforming to correspond ing faces of the nut and having one Wall inclined to the axis of the cylinder and of less depth than others, whereby the cylinder may be driven by said shaft or may be'detached therefrom after slightly spreading the cylin der from the corresponding end of the tub,

2. In a device of the character described, a frame, a tub supported by said frame, a cylinder rotatable in said tub about a horizontal axis, a cylinder driving shaft co-axial with said cylinder'and projecting through the end Wall of the tub, a nut on the inner end of said shaft, abearing for said shaft,

said bearing being in sealed relation to the end of the tub, means for sealing the joint between the nut and the bearing, a bracket secured to the adjacent end of the cylinder, said bracket having therein a socket in Whic said nut is detachably received, Wh cylinder may be driven by said and a closure for said opening, said closurehaving slotted projecting portions adapted to be slid longitudinally of the cylinder until they are received between the corresponding heads and the body, and means for.

retaining the closure in the last named posi- GlOIL A. Washing machine comprising a tub, a casing mounted on the outside of one end of the tub, said casing having a perforated boss projecting into the tub, a cylinder in.

the tub, a driving shaft for the cylinder pro ecting through the boss, at driving element secured to the inner end of the shaft,

said element constituting the support forthe adjacent end of the cylinder and forming therewith a detachable driving connection, and a gland secured to the driving element and preventing seepage of liquid in the tub into the bearing between the driving shaft and the boss.

5. A Washing machine comprising a tub, a casing mounted on the outside of the tub, said casing having a bearing, a cylinder in the tub, a driving shaft in the bearing and projecting into the tub, a driving element secured to the inner end of the driving shaft, said element constituting the support and forming therewith a detachable driving connection, and a packing gland for closin the joint between the driving element an the casing and thereby preventing seepage of liquid into the bearing,
